Hi, I use html5-qrcode in Blazor Webassembly PWA (chrome latest version) on android (xiaomi 9t). Sometimes, at random, onScanSuccess give me a wrong code. Does it happen to you too? What could it depend on? Thank you

Some times also onScanSuccess is fired 2 or 3 times sequentially, last time have the correct code, but first and second a wrong code.

Update. Using timer to filter different codes detectd in a tight interval, I managed to get a satisfactory result, with the device I'm using.
